CVE-2025-48071 (GCVE-0-2025-48071)

Vulnerability from cvelistv5 – Published: 2025-07-31 20:13 – Updated: 2025-07-31 20:22

Title

OpenEXR's Forged Unpacked Size can Lead to Heap-Based Buffer Overflow in Deep Scanline Parsing

Summary

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.3.2 through 3.3.0, there is a heap-based buffer overflow during a write operation when decompressing ZIPS-packed deep scan-line EXR files with a maliciously forged chunk header. This is fixed in version 3.3.3.

Severity

8.4 (High)
